Another Exciting Discovery with my DVX200

Vaughan Wood

Well-known member
Oh, yes, three weeks after receiving my DVX200 back with a new menu switch in place, and working well, I had the opportunity to discover another new way for the camera to pack it in.

We are in our heavy dance concert season and last night, while in the middle of a concert, (just as the tiny tots came on, you know, the ones the Mums REALLY want to see), the camera LCD stated to freeze on me, as though I was shooting with the shutter speed of 1/2 a half a second or so.

This freaked me out , but everything else was still looking O.K., the recording lights were on and audio levels still working, so I kept going.

At the end of that item, I decided to turn it off, but it had completely frozen on me, all recording lights and LCD items were locked, as was the on/off switch.

As the next item was starting, I was still unsure whether anything was going to the card (a Lexar 250 GB) in HD, or the backup card (same type of card in second slot using 8MB backup mode).

By the end of that item, I pulled the battery out and re-inserted it, and rebooted. When it came up, it repaired the data on both cards (very quickly, taking only about 10 seconds for each card), and recorded the rest of the night O.K.

When I got home, I found out both cards had stopped as soon as the LCD stuttering had occurred, and I had lost two items.

The only thing my other cameraman and I can think of is the camera ran short of power - battery is a large one and was only used for 1/2 an hour before the disaster. It went the rest of the night on that battery.
Both cards stopped at the same place and have been used most days in the last two weeks. No trouble getting the info off them, or for the rest of the night.

That's twice in a month the camera has packed it in, my confidence in the camera is now very low!

I have to go out this morning (Saturday) and do it all again, with another 4 hour concert today and one tomorrow.

I'll run the camera on AC power today, as I have to record in 4K for these next two concerts, and record to an external DVD recorder at the same time.

Wow, this is enough to make me retire early!

Cheers, Vaughan
 
Hi Vaughan,
I've had that exact problem before, but only once. I was shooting a guitarist in my home studio and saw the stuttering LCD and unresponsive system. Even flicking the physical power switch to "off" did nothing, the camera remained on. Luckily, I was in such a controlled environment that I just asked the musician to stop. I pulled the battery out with the camera still on, put it back in, powered it back on, repaired the clips, and went ahead with the next recording. Battery level was high, card was recently formatted.
I don't recall whether I lost prior footage or not, we just started from the beginning with a new take. Sorry this happened to you.
The DVX200 has been my main camera since February, and I've only had that happen to me once. No rhyme or reason there...there are other cameras out there with a more pure run-and-gun feel than the DVX200, and perhaps the operating system on this one is just complex enough that it can occasionally trip over itself.

Hi EdRicker,

Yes, that was virtually identical to what happened to me. Probably worse when you're down the back of a large dark hall! Scary!

No problems with a 4 hour concert today, but I made sure I used AC power.

Will be interesting to see if anyone else pops up with the same experience!

Cheers,

Vaughan
 
Hi Vaughan and Ed. Sorry to hear about these incidents, that is very scary. I was shooting a conference last week and if that had happened to me, I would have broken out in a cold sweat.

Question - what batteries are you guys using? I'm using the SWIT batteries and have not had a problem with them yet.

I had card issues with Lexars when I used the 95MB/s cards (recording dual codec) but that went away when I upgraded to 150's. Not the same problem, but I wonder if this is related to cards or batteries.

Also dreading the possibility of my jog dial breaking like yours did...Israel isn't exactly customer service friendly like the US or UK. It's the only thing I miss about London! Be thankful you've got Panasonic labs willing to help!
 
I am using SanDisk Extreme 128 GB cards and Panasonic batteries. I was at a shoot a few months back; everything had been working fine. I have a habit of shutting down anything on battery power in between interviews. Once it refused to turn back on. I pulled out the battery and reseated it and it came on just fine. It's never happened again and I haven't had an issue during recording.

I use a couple Panasonic VW-VBD58 battery packs, and I also use the IDX SL-VBD96 high-capacity version as well. Can't remember which one I used the day that the camera froze, but honestly I've used each battery so often that to attribute it to a battery issue seems like flaky reasoning. My cards are Lexar 1000x 128GB SDXC UHS-II 150mb/s U3.

It really just seemed like a fluke, and it's one I've never had the "pleasure" of duplicating. Hoping for the best, for all of us!

Hey EdRicker,

What kind of battery life do you get on your IDX SL-VBD96 battery?

Also... I like your YouTube channel :)

Not so much flaky reasoning as grabbing at straws! Just trying to figure out what it could be beyond a fluke. It's not something I would want to happen in an uncontrolled environment...

I has my iris ring seize up and I thought something had gotten into it. I was shooting at a conference and it was really tough to turn, I almost panicked. Then I realised my XLR cable had gotten caught on the right side between the cam and the ring. D'oh! Felt like an idiot. So you see, that fear isn't entirely healthy when at a gig, hence my need to understand what the issue could be. Even when it's nothing I break out in a cold sweat because you never know when your gear is going to fail you suddenly.
 
Can we do some detective work? Let's document the situations when the unit froze.
F/W version installed
Description of freeze, and consequences (lost data, etc.)
On battery or A/C? If battery, what type (size, vendor)?
System Mode settings at the time
2 Slot settings
Specs of SD card(s) in use
Anything else you think might be relevant

The more data we can send to Panasonic, the more able they'll be to correct it.
 
So far as I know the DVX200 doesn't actually have the necessary extra contacts to make use of a SDXC UHSII card and will default the card to UHSI. It will then be slower then a fast UHS1 card like the Sandisk Extreme pro U3 SDXC UHS card! I tried a Lexar UHSII in a BM video assist which also only uses UHSI cards. It was too slow and dropped frames.

I've never really tested out the full life of it...but honestly I've never had it run out on me. I usually prefer using the smaller batteries though if I'm doing handheld or glidecam work to minimize weight, so I'm more familiar with the smaller battery run times.
I did a roughly 6 hour shoot the other day on a tripod though with the IDX battery, and it still showed 2 lights out of 4. Pretty hefty battery!

Thanks for watching!

Date of freeze: 10/24/16
F/W version installed: 1.81
Description of freeze, and consequences: Unresponsive system, stuttering lcd, said it was recording but wouldn't respond or even turn off without battery extraction.
Turning on the camera, I hit repair clips, but the clip it was recording when it crashed did not actually save...The only two clips that actually saved were the one before the crash occurred and the one I started after rebooting the system.
On battery or A/C? Battery, pretty sure it was the Panasonic VW-VBD58 battery
System Mode settings at the time: 1080p @ 29.97fps - MP4 - no phantom power -
2 Slot settings: off
Specs of SD card(s) in use: Lexar 1000x 128GB SDXC UHS-II 150mb/s U3
 
As I tried to explain in an earlier post the DVX200 doesn't actually support your Lexar 1000x 128GB SDXC UHS-II 150mb/s U3 card, as I doesn't have the necessary extra connectors the card needs to work as a UHSII. Therefore the camera will use it in the UHSI mode and in my experience your Lexar will become slower than a fast UHSI card like the Sandisk extreme 95mb/sec UHSI. As there are no equivalent connectors in the camera it just cannot deliver 150 mb/sec and might instead well contribute to the problems you have observed. If you compare the connector tabs on a UHSI card to those on a UHSII you'll immediately see where the problems lie.
 
I've done 7 hr time lapses with the big IDX battery and the pull out view-screen closed to save power and still had at least 2 lights of reserve left. 7 hours of run time with the screen open sounds about right - maybe even a bit more. It's pretty stout.

I've never had a problem directly attributed to recording with the cards I own. I own two of the same style cards and other than the recording issue that I consider a fluke, one day out of many, I've never had another issue. I don't think it's the card. I've had phenomenal success recording 4k DCI 100mb/s, UHD 60fps 150mb/s, and 1080p 200mb/s, so for me to attribute a 1080p 50mb/s recording failure on the card itself is an error in reasoning in my opinion.
I also have a collection of 4 Transcend 32GB SDHC Class 10 UHS-1 cards, and I used them before I bought my Lexars. No difference in performance. I can still record 4k DCI on the Transcend 32GB SDHC Class 10 UHS-1 without error.

But that's in a BM video assist, have you tried them in the DVX itself? I don't know the tech to be honest, but I do know that when shooting dual codec on the 95's, the cam stopped recording quite a few times. When I switched to the 150's, no probs since.
 
Whats about the temperature (environment, battery, card)?
As i understood, in both cases the recording time had been long.
In my experiences, cards geting hot in this cases.
And the battey is getting very warm in cause of the useless an heat accumulation battery door.

No, my cam was on for just a few minutes indoors when it happened. Neither heat nor runtime were the issue.
 
I'm sure your observations are very valid> All I'm saying is that the dvx200 is limited to UHSI and cannot take advantage of the speed advantages of UHSII cards. It can use the cards but will revert to UHSI and it's anyone's guess what speed it will arrive at without using the additional contacts on the card. I've had some problems with UHSII cards in UHSI devices but your problems might well not be attributable to the card.
Still: there's no gain in buying UHSII if the camera is UHSI: http://pro-av.panasonic.net/en/products/ag-dvx200/pdf/ag-dvx200_spec.pdf
